Book Description
The braking performance of a nine-place, light, twin-engine airplane was evaluated on comparative grooved and ungrooved surfaces of the landing research runway at NASA Wallops Station. The test airplane was equipped with manual braking on the main wheels of the tricycle landing gear, and its weight varied from 33.4 to 35.6 kN (7500 to 8000 Ib). The test results indicate that pavement grooving significantly improves aircraft braking and directional control on wet runways. Measurements and observations of airplane tire treads made during this test program showed no indication of unusual wear and/or damage attributable to grooved surfaces. Comparative braking data obtained with a jet fighter and a civil and a military jet transport are also presented.
